Obsidian hydration dating lab mbti dating service
It is an absolute dating method, and does not depend on comparison with similar objects (as does obsidian hydration dating, for example).
The thermoluminescence technique is the only physical means of determining the absolute age of pottery presently available.

In all, close to two dozen physical quantities must be accurately measured to establish the relationship between doses of different kinds of radiation and light output, and to compute dose rate.
Prehistoric rinds can vary from less than 1 micron (µm) to more than 50 µm, depending on the length of time of exposure.
By measuring the thickness you can easily determine if one artifact is older than another (relative age).
Welcome to the K12 section of the Radiocarbon WEBinfo site.
Chronological sequence is all that is really required.They used pottery and other materials in sites to date 'relatively'.They thought that sites which had the same kinds of pots and tools would be the same age.When a fresh surface of obsidian is exposed to the atmosphere, as when it is broken to make a stone tool, more water is released and the rind begins to grow again.That new rind is visible and can be measured under high-power magnification (40-80x).
I have tried here to answer some of the frequently asked questions that I receive from students via email, as well as providing some basic information about scientific dating methods.
